Sorry that it took a while, but i just had the time to do it. The torrent is fine. It seems that the problem was really that it was copied into my main directory (so just "D:" and no sub folder) and later copied it into a different folder. So always choose a real sub folder and don't unzip it.
Absolutely my mistake. I should've just changed the directory to unzip to beforehand.
I hope that made sense since english isn't my first language and coming up with those computer terms in a different language is hard.
